The 45-year-old woman was referred to an orthopedic surgeon with complaints of pain in the right hip joint which she had endured for over a month. The pain was worse when walking. Previously, she had never been treated and had not sought medical help. After a physical examination, the orthopedic surgeon referred her for an ultrasound (US) of the right hip joint.
The US examination revealed the following: on the right hip joint (left image), the contour of the femoral head is uneven and deformed, cartilage visualization is unclear and the joint capsule is thickened. For comparison, the left hip joint (right image) showed the following: the contour of the femoral head is even, cartilage surface is smooth, homogeneous, joint capsule is normal.
